  imidacloprid
Determination of the Insecticide Imidacloprid in Potato (Solanum tuberosum L.) and Onion (Allium cepa) by High-Performance Liqui
      
A high-performance liquid chromatography (HPLC) method has been proposed for the determination of imidacloprid residues in fortified potato (Solanum tuberosum L.) and onion (Allium cepa) and in treated potato and onion samples.
      
Sample preparation consisted of dichloromethane extraction of imidacloprid from the plant material, followed by purification of the obtained onion extract on an LC-Florisil disposable cartridge.
      
The HPLC-diode-array-detection (DAD) method has been developed on reversed phase for separation of imidacloprid with isocratic elution with a mixture of 0.01 M phosphate buffer (pH 3.15) and acetonitrile (75 : 25, v/v).
      
Spectral data obtained with DAD allow the identification of imidacloprid residue.

A reversed phase HPLC method is described for the determination of residues of imidacloprid. The method uses PE/HS5C18(5μ 4.6 mm×125 mm) column and methanol (35+65) as mobile phase, with UV detection at 269 nm. The average recovery is 101.6%, the detection limit of imidacloprid is 0.35 ng, the sensitivity, accuracy and precision are good. This method is applied to assay the residues of imidacloprid in apple samples.
